OpenShift SSH Private Key¶

This parameter stores the private portion of the SSH key pair used for secure access to OpenShift cluster nodes. This key is automatically generated during cluster deployment.

Requirements¶

Must be a valid ED25519 SSH private key
Must be kept secure and not shared
Must correspond to public key in openshift/ssh-key-pub
Should only be used for cluster administration

Usage¶

The key is automatically generated during the openshift-cluster-tools task:

# Generated using
ssh-keygen -t ed25519 -N '' -f /root/.ssh/cluster_ssh_key

# Used for:
- Initial node access
- Debugging cluster issues
- System maintenance
- Core dumps and troubleshooting

Notes: - Never share or expose this private key - Key is automatically stored in profile during generation - Used by the OpenShift installer for initial node configuration - Access should be strictly controlled
